Bolivia and Paraguay are the landlocked countries in South America.

• Bolivia is bordered by Brazil, Peru, Chile, Argentina, and Paraguay, with no coastline, though it maintains a navy for river access and lake routes.

• Paraguay is landlocked but has access to the Atlantic Ocean via the Paraguay–Paraná river system, and it borders Argentina, Brazil, and Bolivia.

If you’d like, I can add quick references or map notes to illustrate their locations and river/ocean access.
